Abstract
An exercise station for use in performing leg exercises has a bench on the front of which an exercise unit with leg engagement arms and a load unit connected to a loaded cable are swing mounted on a horizontal swing axis. A two-bar linkage is pivotally connected to the units and has over-center extended and folded positions when the exercise unit is in raised and lowered exercise positions, respectively, whereby exercising swing movement of the exercise unit also swing moves the load unit by way of the linkage.
Claims21
An exercise station comprising:
- a support frame;
- a load unit and an exercise unit swing-mounted on said support frame for relative swinging movement, said exercise unit having first and second exercise positions for performing respective first and second exercises each causing swinging of said exercise unit in the same exercising direction;
- and
- said load unit having different positions relative to said exercise unit when said exercise unit is in its first and second exercise positions;
- a linkage constantly interconnecting said units such that when said exercises are performed, swinging movement of said exercise unit in said exercising direction causes like swinging movement of said load unit, said linkage having an extended condition when said first exercise is performed and having a folded position when said second exercise is performed whereby said load unit has said different positions relative to said exercise unit.

An exercise station comprising:
- a frame having an elevated support at a front end;
- a load unit and an exercise unit swing-mounted on said support for relative swinging movement on the same swing axis, said exercise unit having a raised exercising position for performing a first exercise and a lower exercise position for performing a second exercise, performing of said exercises causing swinging of said exercise unit in the same exercising direction;
- a cable attached to said load unit for transferring a load to the load unit to resist swinging movement of the load unit in said exercising direction;
- and
- a linkage spaced from said swing axis and constantly interconnecting said units such that when said exercises are performed swinging movement of said exercise unit in the exercising direction is resisted via said linkage by the load on said load unit from said cable, said linkage having an extended condition when the first exercise is performed, and having a folded position when said second exercise is performed whereby said exercise units can be operated in said alternative exercise positions.

An exercise station comprising:
- a body support having an upwardly projecting post at an elevated front end;
- a load unit and an exercise unit swing-mounted on said post on the same swing axis for movement relative to one another in front of said body support, said exercise unit having a raised position for a leg curl exercise and having a lowered position for a leg extension exercise;
- a two-bar linkage pivotally connected at opposite ends to said exercise unit and load unit at first and second pivot axes, respectively, and movable between a folded rearwardly directed condition when said exercise unit is in its lowered position, and an extended condition when said exercise unit is in its raised position;
- said linkage having an elbow pivot between its two bars which has a pivot axis located in respective over center positions behind respective imaginary straight lines through said first and second axes when said exercise unit is in its said positions to thereby keep said exercise unit in the selected of said positions so that said exercise unit will be constantly coupled by said linkage to said load unit;
- a spring extending between said linkage and said exercise unit for biasing said linkage into said over-center positions corresponding to said raised and lowered positions of said exercise unit;
- and
- a lever connected to said exercise unit for selectively manually swinging said linkage out of said over-center positions in opposition to the bias of said spring so that said exercise unit is then free to be moved between said raised and lowered positions independently of said load unit.
